Computer won't recognize USB flash drive.

Hi,

1.     Which troubleshooting steps have you tried?

2.     Does any other Universal Serial Bus controllers (USB) device get detected in the computer?

3.     What exactly happens when you connect the flash drive to the computer? Any error messages received?

4.     Any changes made to the computer prior to the issue?

5.     Does the device work in any other computer?

Method 3:

Let’s check if the USB drive gets detected in Disk Management.  Follow the steps given in the following article to do the same:

Check whether a Drive letter is assigned for USB drive, if not assign a drive letter and check if it helps.

my computer want recogonize my travel drive

Normally when i plug my flash drive into my computer it accepts it, but today when i get home from out of town and tried to plug my flash drive into my computer it want recognize it. What is the problem? I troubleshoot and its telling me nothing is wrong/

I had a similar problem with a micro-duo USB memory stick that couldn't be recognized on my computer. I resolved the problem by pure chance. Here is what I did:

1. Plug the problematic USB flash memory stick in your computer
2. Go to Control panel
3. Go to Device Manager
4. Click on Portable devices
5. You should find there an "unknown device". It should be the USB flash memory that can't be recognized by your computer.
6. Right-click on the "unknown device"
7. Click on "uninstall". Your computer should uninstall the USB memory stick and then automatically re-install it. After reinstallation, the USB memory stick should be visible on your computer.
8. (Optional)  You may see a pop-up notification asking you to fix and scan the USB memory drive (i.e. the stick). You should do it if the memory drive is empty. Otherwise, you should first backup the data which is stored on that drive and then allow the computer to do fixing and scanning.

I hope this will help.

Cheers
